Application filed August 28, 1913. Serial No. 787,186.

To all whom t may concern lle it known that l, FRANK V. Risinonn, a citizen of the United States, residing at lioungstown, in the county of Mahoning and State of Ohio, have invented a new and useful Gasllamp, of which the following is a specification,

rlhe present invention relates to improvements in gas lamps, and more particularly to a gas lamp of the inverted mantle incandescent type, the primary object of the invention being the provision of a lamp of this character provided with a stop cock and needle valve disposed under the ref'lector for convenience of operation and for protection of the working parts from ice, snow, rain and other conditions that prove detrimental to the operation of the lamp and prevent the production of a maximum illumination from a minimum amount of gas.

A. further object of the present invention is the provision of a gas lamp of the Bunsen type in which the entrance to the bunsen is at a low point in comparison with the outlet, so as to lessen the back pressure of -flow of the mixture flowing between the gas valve and the inantles.

i still further object of the invention is the provision of a gas lamp in which the cluster body is composed of an upper and a lower section, the lower section being removable to be lowered and swung to one side when necessary to permit of the proper cleaning of the filtering gauze at the end of the bunsen.

fr still further object of the present invention is the provision of a lamp having means by which the air supply previous to entering the inlet of the lunsen tube will not be subjected to undue heat and will 'thereby contain the greatest amount of oxygen possible to assist in the proper miX ture of before the delivery thereof to the mantle.,

fr still further object of the invention is to provide a convenient means by which the globe may be quickly removed for cleaning and other purposes, and to improve the general construction and arrangement of a lamp of this character.

lllith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the. details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of tne invention herein disclosed can be made within the scope of what is claimed without so departing from the spirit of the invention.

In the drawings Figure l is a vertical central sectional view through the complete lamp embodying the present invention, said section being taken to show the full Bunsen es tube of the lamp. Fig. Q is a top plan view of the upper spider of the lamp. Fig. 3 is a bottom plan view partly in section of the cluster and the inner cylinder of the lamp. Fig, 4l is an enlarged detail sectional view 7o showing the connection of the Bunsen carrymg member to the main supply pipe. Fig. 5 is an enlarged detail view of the gas control. Fig. 6 is a detail view of the valve retaining spring clip. Fig. 7 s an enlarged 75 detail view of the globe attaching clamp in relief position. Fig. 8 is a side elevation of the cluster carrying ring, and through the Bunsen carrying portion. Fig. 9 is a similar view showingA the lower or cluster cara0 rying section lowered and swung to one side, Fig. l0 is a bottom plan view of the parts as shown in Fig. 9.

Referring to the drawings, the numeralwl designates a gas supply pipe, which constitutes a main support for the lamp, a coupling 9. being connected thereto and forming a means to connect the Bunsen tube and cluster carrying stem 3, said stem 3 being extended downwardly as at 4land having a 9o channel 3 in communication to receive the gas from the supply pipe. An elbow 5 is in communication with the channel. 3 and has led therefrom and downwardly, the inclined gas supply pipe 6 which leads into the valve` e5 casing 7. rlhis valve casing 7 has also led from the bore thereofJ the pilot tube 8 whereby a constant flame may be maintained within the cluster so that the same will be ignited by simply turning on the gas by the ias manipulation. of the valve 9. rThis valve 5) is provided with a stem i0, which as shown in Fig. l entends downwardly at an angle and in ready access for manipulation, a spring clip l1 being provided to maintain iss the same in resiliently seated relation to the casing 7. The gas directing nozzle 12 is formed integral with the casing 'Y at one end thereof and is provided with a needle valve l'lfwhereby the jet of gas emitted therefrom its may be regulated to an exactness. This tube 12, as clearly shown in Fig. 1, is disposed to project inclinedly upward into the inclined inlet 14 of the Bunsen tube 15, the outlet end of which empties into the chamber 16, which is composed of two members, the lower cluster section 17 of which is connected to the upper section by means of the screw 17, and carries the mantle carrying tubes 19 disposed in the outlets 13 of the section 17. The usual inverted mantles 2O are employed. Disposed within the chamber 16 at the outlet of the Bunsen tube 15, is a gauze 22, which is so positioned as to permit the gas to be properly supplied to the mantles 20 and yet at the same time due to the fact that the member 17 is detachedly secured to the member 13 of the chamber 16, is readily accessible for cleaning or removal.

To permit the cluster section 17 to assume the position, as shown in Figs. 9 and 10, a rod 100 is carried by the section 17 and slides through the apertured projection 101 of the section 16, the knob 102 limiting the downward movement of the section 17. Thus to move the section 17 from the position shown in Fig. S, to that shown in Figs. 9 and 10, the screw 17 is removed and the section 17 can then be lowered and be turned or swung to the side. To assist in positioning the sections before connecting with the screw 17 the short pin 103 registers with and enters the aperture 104, as the section 17 is pushed upwardly. lThe flared rim 21 is secured to and carried by the lower section 17 while the globe carrying` rim 23 is carried by the uppe section of the chamber 16, the air directing cylindrical member 24 being connected thereto and extending upwardly and approximately about the Bunsen tube portion of the member 4. The reflector member 25 is connected at its upper end to the upper edge of the cylindrical member 24, and extends outwardly and above the valve casing 7 and the valve stems 10 and 13, thus providing a means to prevent water or rain from aecting the valve casing or entering the lower end of' the Bunsen tube. At one side of the rim 23 is a plate 26, which as .clearly shown in Fig. 3, is provided with three apertures 27, 28 and 29 for the reception respectively, of. the pilot tube 8, supply pipe 6 and the gas directing tube 12, said plate being further provided with a plurality of apertures 30, which provide a means for admit-ting air into the globe By this means, the air admitted through the apertures 30 is cool. The air not havingy been heated, will carry with it the maximum amount of oxygen.

To the rim 23 is attached two pins 31, and

i valved a ivoted cani lever 32 said lever 32 being resiliently mounted as at 32', so that the glass globe 33 may be properly supported and yet easily removed for cleaning and re- I let end of the Bunsen 1 with the reflector.

newal. The outer cylinder 35 is provided with the lower apron portion 34 which is disposed adjacent to the upper end of the reflector or hood 35, the same being supported from the spider 36, which is connected to the pipe 1, said spider 36, as clearly shown in Fig. 2, being provided with the outstanding radial arms 39 which provide a means for properly supporting the air directing flange or rim 38 and the dome 37.

From the foregoing description, taken in connection with the drawings it is evident that the heat caused by the burning gas within the mantles 20 will cause air to flow and follow the direction of the arrows, said air being admitted primarily beneath the apron 34 and through the openings 25 of the rim 23 into the globe, the only outlet being upwardly around the cluster through the cylinder 24 into the upper portion of the cylinder 35 and through the spider 36 and downwardly below the rim of the dome 37 and through the outlet space between the periphery of the dome 37 and the rim 38. By this means the lamp is properly ventilated, and the parts are maintained at the lowest possible temperature.

By disposing the valve 10 and the gas admitting tube or nozzle 12 in the position as shown, the inlet end of the Bunsen tube being curved downwardly instead of upwardly as is the usual custom, the parts are protected by the rim of the reflector 25, and the valve stem 10 is readily accessible for manipulation to control the flow of gas to the Bunsen tube. It is also apparent that the main supporting member of the entire lamp is the stem 3 of the member 4, and that the strain of support is equally disposed with relation to the supplying and supporting pipe 1, said supporting pipe 1 being connected to the outlet of any gas pipe as a pendant and as is the usual practice in attaching gas fixtures.

What is claimed is:

1. A gas lamp, having a burner cluster, a Bunsen tube with its outlet concentric thereto and its inlet inclined downwardly and outwardly, a reflector slrirting the inlet of the tube, a globe supported by the reflector, and a valved gas nozzle beneath the reiiector exteriorlv of the globe and emptying into the inlet of the tube.

2. A gas lamp, having a burner cluster, a Bunsen tube with its outlet concentric thereto and its inlet inclined downwardly and outwardly, a reflector skirting the inlet of the tube, a globe supported by the reflector, a

gas nozzle beneath the reector exteriorly of the globe and emptying into the inlet of .the tube, and an air directing cylinder disposed above the burner cluster and through the wall of which projects the intube in coperation ico 3. A gas lamp, having a burner cluster, a Bunsen tube with its outlet concentric there to and its inlet inclined downwardly and outwardly; a reflector skirting the inlet of the tube; an air directing cylinder disposed above the burner cluster; an outwardly projecting globe carrying rim adjacent the lower end of the cylinder, a valved gas nozzle in the annular space formed by the rim, cylinder and reiiector said nozzle emptying into the inlet end of the Bunsen tube; and a globe supported by the rim.

4. A gas lamp, having a Bunsen tube, a sectional cluster member into which the tube empties, a single fastener concentric of the sections, and a pin slidably mounted in one section and fast to the other section, whereby when the fastener is released., one cluster section may be slid downwardly and swung to one side.

In testimony that claim the foregoing as my own, I have hereto aXed my signature in the presence of two witnesses.
